10.14. Obtaining Commons Net

10.14.1. Problem

You need to use Commons Net to write a simple FTP, SMTP, or POP3 client.

10.14.2. Solution

To use Commons Net in a Maven 2 project, add the following dependency to your project's pom.xml:

Example 10.3. Adding a Dependency on Commons Net

    <dependency>
        <groupId>commons-net</groupId>
        <artifactId>commons-net</artifactId>
        <version>2.0</version>
    </dependency>

If you are not sure what this means, I'd suggest reading Maven: The Definitive Guide. When you depend on a library in Maven 2, all you need to do is add the dependency groupId, artifactId, and version to your project's dependencies. Once you do this, Maven 2 will download the dependency and make it available on your project's classpath.

10.14.3. Discussion

Commons Net contains some simple clients for commonly used network protocols, such as FTP, TFTP, Telnet, NNTP, POP3, and SMTP. Protocols are supported by collections of classes in packages dedicated to these protocols. For example, FTP is supported by a set of classes in the org.apache.commons.net.ftp package, including FTPClient and FTPFile; and SMTP is supported by classes in the org.apache.commons.net.smtp package, including SMTPClient.
